study of ixazomib and romidepsin in peripheral t-cell lymphoma (ptcl)

Conditions: Lymphoma, T-Cell, Peripheral

Summary: single arm phase i/ii study of ixazomib and romidepsin in relapsed/refractory ptcl. each cycle is 28 days. patients will continue to receive therapy until progressive disease, unacceptable toxicity, or if any other withdrawal criteria are met. the phase i study includes three dose levels. the phase ii study will include treatment with ixazomib and romidepsin at the mtd established in the phase i study.
